Scientific paper

The poleward motion of the auroral convexity is explained by the heating of the magnetospheric plasma inside a region of field-aligned currents and longitudinal potential-difference. The heated magnetospheric plasma moves away from the earth. If the Hall conductivity of the ionosphere below the heated-plasma region increases, the polarization electric-field inside this region acquires a poleward component, and the velocity of the heated region acquires a westward component. Expected poleward velocities of the heated plasma agree with observed velocities of the auroral convexity and amount to several km/s at the ionospheric level.
